Eaton - Westinghouse 11-300 - Breaker MCC Bucket - 5 A, 240 V, 9" Height, 3 P | AmpState

Meet the Eaton - Westinghouse 11-300 Breaker MCC Bucket — a purpose-built upgrade for industrial power distribution and motor control centers. This unit is rated 5 A at 240 V and is designed to drop into the 11-300 MCC family, delivering reliable protection for motor loads while preserving the integrity of your control architecture.

Built around a compact 9" vertical frame, this MCC bucket combines space efficiency with rugged durability. It’s an ideal choice for retrofit projects, OEM replacements, or custom MCC configurations where every inch matters and consistent protection is essential.

Why this MCC bucket stands out

• Exact OEM compatibility: engineered to match the 11-300 family’s mounting pattern and electrical characteristics for a plug-and-play retrofit.
• Three-pole protection: 3P configuration supports standard 3-phase motor loads in demanding industrial environments.
• Seamless integration: designed to work with existing Eaton-Westinghouse bus bars and enclosure rails, minimizing modification work and downtime.
• Reliable performance: rated 5 A at 240 V (three-phase, 60 Hz) to safely interrupt motor startup and running currents.
• Compact footprint: 9" tall frame is ideal for tight MCC decks, freeing space for other protection and control devices.
• Versatile applications: suitable for new installations, OEM replacements, or retrofits where OEM parts support lifecycle consistency.

Use cases and practical scenarios

- Retrofit a failing breaker bucket in an existing 11-300 MCC without rewiring the entire enclosure.

- Upgrade to an OEM-recommended component to maintain protection characteristics and trip behavior operators rely on.

- Configure custom MCC layouts where multiple buckets share a standard 9" frame and a 3P protection scheme.
